Х=29+13
Х=42

Ответ: 42

Answer 2

Solving Equations:

Let's solve the given equations step by step.

1) Equation 1: - The equation is: x/72 - 13/72 = 29/72 - To solve for x, we can start by adding 13/72 to both sides of the equation. - This gives us: x/72 = 29/72 + 13/72 - Simplifying the right-hand side: x/72 = 42/72 - Now, to solve for x, we can multiply both sides by 72. - This gives us: x = 42

2) Equation 2: - The equation is: (29/42 - a) - 13/42 = 11/42 - To solve for a, we can start by adding 13/42 to both sides of the equation. - This gives us: 29/42 - a = 11/42 + 13/42 - Simplifying the right-hand side: 29/42 - a = 24/42 - Now, to solve for a, we can subtract 29/42 from both sides. - This gives us: -a = -5/42 - Finally, to solve for a, we can multiply both sides by -1. - This gives us: a = 5/42

Solutions:

1) For the first equation, the solution is: x = 42 2) For the second equation, the solution is: a = 5/42
